Lateral-Take-Up Devices for Locomotive- Axles, of which the following is a specification.

My present invention relates generally to railwa appliances, and more particularly evice for taking up the lengthwise thrust of locomotive axles, my object being the provision ofan improved construction along the lines of my Patent 1,202,701, granted October 24, 1916.

In my patent just referred to, inner and outer take up sections were described and claimed adjacent each of the driving boxes, the inner sections at each side being keyed or otherwise fastened to the axle, and the two sections having abutting flanges, upon disconnection of which, the outer and movable section might be adjusted with respect to the inner stationary section.

In my present improvements I purpose to avoid the expense of inner sections formed in the'manner shown in my patent, and to substitute therefor collars united to theaxle in such a manner as to form sub-- stantially a part thereof, the collars themselves taking the place not only of the inner sections of the Patent 1,202,701, before referred to, but of the flanges as well, as the collars present effective means in opposition to the inner flanges of the outer sections, which latter may be constructed substantially like those shown .in my patent referred to.

In the accompanying drawing forming part of this invention Figure 1 is an elevation of a portion of an axle equipped with my present improvements, partly broken away and in section.

Fig. 2 is a transverse section through one of the collars, and,

Fig. 3 is a face view thereof showing a sectional form.

Referring now to these figures, my improvements, as in my patent referred to above, are installed and utilized in connection with a locomotive axle A, at a point spaced on which, with respect to its driving boxes, of which one appears at B, in Fig. l, in turn adjacent the wheel -C, my invention purposes the connection of an annular collar 10 haw ing a sharply tapered opening whose point of smallest diameter adjacent one side of the collar is slightly greater than the diameter of the'axle A, so as to admit of disposal of the collar on the shaft in the position shown in Fig. 1.

If the collar 10 is disposed upon the axle A in the first instance, or where it is necessary to dismantle the axle assemble for other reasons, a collar in one piece is utilized On the other hand, as shown in Fig. 3, the collar may consist of segments 10, so that they may be placedcircumjacent the axle without dismantling the parts carried thereby,

the abutting ends of these segments being welded, fused or otherwise connected to form an integral one piece structure at the same time and possibly by the same means utilized as presently described'for connecting the collar to the axle.

t The. taper of the opening through the collar l0provides for the convenient reception of a fusing metal 11, which is caused to flow into the space betweenthe collar and the axle as seen in Fig. 1, fusing the collar to the axle and connecting and supportingthe same in. substantially an integral manner thereto.

As seen in Figs. 2 and moreover, the collar 10 has openings 12 therethrough for the reception of bolts 18, as seen -in Fig. 1,

' which connect the collar to the inner flange 14 of its respective adjustable section 15, the latter having an outer flange 16 opposing the inner face of the driving box B, and being in segments having longitudinal flanges 17 connected by bolts 18. 1

It is obvious therefore, that by. disconnectin'g the inner flange 14 of the outer section 15 from the collar 10, the outer section 15 may be adjusted toward the driving box B to take up any play resulting from undue wear, and that spacers, liners, or other devices of similar nature may be inserted between the collar 10 and the flange l4 and the bolts 13 thereafter reintroduced to again rigidly connect the adjustable section 15 in adjusted position. 1

It is obvious, therefore, that the strain upon theco llar 10 is in a-direction away from the adjustable-section 15, and to this end the collar'may' be further braced .-in its connected relation to the axle A by the utilization of triangular bracing members 19 in spaced relation around the axle A, whose right angular faces are welded, fused or abutment section being in the form of a collar provided with a tapered opening through which the axle extends, a fusing metal in the space within said collar formed by said tapering opening around the shaft to rigidly connect the collar with the shaft, and means for connecting the adjacent portions of the collar and. said adjustable section.

axles comprising an adjustable section and a stationary abutment section, said abutment section beingin the form of a collar provided with a tapered opening through which the axle extends, a fuslng metal in the space within said collar formed by said tapering opening around the shaft to rigidly connect the collar with thelshaft, means for connecting the adjacent portions of the collar and said adjustable section, and triangular bracing members disposed in spaced relation around the'axle and connected to the latter and to theinner face of the collar for the purpose described.
